windows2003 server mysql scheduled backup every day

1.php uses mysqldump to back up the database, the code is as follows:

<?php 

/**
 * 数据库备份
 */

$sqlname = $argv[1]; //接受bat或cmd传过来的第一个参数  要备份的数据库名
$day = $argv[2]; //接受bat或cmd传过来的第一个参数   备份数据保存天数

/*备份保存$day天，老数据删除*/
$old = 'e:/wamp/db_backup/'.date('Ymd',strtotime("-".$day." day")).$sqlname.'.sql';
if(file_exists($old)){
    unlink($old);
}

//备份数据库
$filepath = 'e:/wamp/db_backup/'.date('Ymd').$sqlname.'.sql';
$sql = 'mysqldump --no-defaults -uroot -p*** '.$sqlname.' > '.$filepath;
exec($sql);

 ?>

2. Run the above php file through bat, the content of the bat file is as follows:

<code><span>e:/wamp/php5<span>.4<span>.44/php<span>.exe e:/wamp/backup<span>.php zzy <span>30</span></span></span></span></span></span></code>

Among them:
e:/wamp/php5.4.44/php.exe: PHP installation path;
e:/wamp/backup.php: PHP file to be run;
zzy: Database to be backed up;
30: Number of days to save backup data.
3. Just add the bat file to the scheduled task.

The above introduces the daily scheduled backup of mysql in windows2003 server, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
